noon BUMPER;

Application filed April 27, 1923. Serial No. 635,064.

1 0 all whom it may concern:

Be it known that I, ERNEST R. MITCHELL, a citizen of the United States residing in Philadelphia, Pennsylvania, have invented a Door Bumper, of which the following is a specification.

One object of this invention is to provide an attachmentparticularly designed for use on doors of motor vehicles which shall be of such construction as to be quickly and inexpensively installed and in which is included novel means for retaining in place a block or body of resilient material. Another object of my invention is to provide a door bumper which shall include a metallic stamping of inexpensive construe tion so formed as to firmly hold in place a block or rubber serving as the door. engaged element.

These objects and other advantageous ends I attain as hereinafter set fortlnreference being had to the accompanying draw I ings in which,

Figs. 1 and 2 are respectively a front and a side elevation showing my invention as applied tothe amb or standing post of a door,

Figs. 3 and 4e are respectively a. front and side elevation of the metallic stamping forming part of my invention;

Fig. 5 is an inverted plan view of the stamping shown in Figs. 3 and t; and,

Fig. 6 is aperspective view ofthe rubber bumper block for use in the bumper above referred to.

In the above drawings, 1 represents the back of a sheet metal stamping having a top 2, bottom 3 and one side t it being noted that the corners uniting the top 2 and bottom 8 with the side i are cylindrically curved or rounded.

The edges of the top, side and bottom are formed with a marginal flange 5 extending outwardly and having also outwardly extending flanges 6 and 7 at the free ends of top and bottom. Countersunk openings 8 are provided in the back 1 for the reception or" screws whereby the stamping may be retained in a suitable form of recess in the door jamb or standing post of a door frame and it is particularly to be noted that such recess for the reception of the stamping may be made by a suitable machine without requiring any hand work whatsoever.

Moreover, when mounted in the recess, the flanges 5, 6 and 7 of the stamping com pletely conceal any spaces or irregularities in the recess of the amb orstanding post in which the body of the stamping is mounted.

Further in accordance with my invention the parts 2 and 3 designated as the top and bottom respectively of the stamping have longitudinally extending ribs 9Q projecting into the hollow of the stamping and designed to enter similarly formed grooves or recesses 11 in the opposite sides of a bumpcr block 10 of rubber or other suitable yielding or resilient material. t will be understood that the grooves 11 are molded or otherwise formed in the blocks before the block is assembled with the stamping. As indicated in Figs. 1 and 2, this block. is of such length that it projects beyond the plane defined by the flanges 6 and 7 and is of such thickness that it likewise projects beyond the plane of the flange 5. Moreover, the recesses 11 are so positioned that the ribs 99 which are angular in cross section tend to draw said block toward the back 1 and into the hollow of the stampii'ig thus assisting in frictionally holding said block in place. In addition, the rubber block is of such dimensions as to tightly fit in the hollow of the stamping and its corners are suitably rounded or curved to permit it to more or less closely fill the same.

With the above described arrangement of parts, the stamping itself may be quickly and inexpensively mounted in the door j a-mb or standing post of adoor frame, after which the bumper block may be put in place where it will be immovably retained in position to properly fulfill its functions.

I claim- The combination in a door bumper, of a recessed metallic supporting structure shaped to receive a bumper block or Viol-d ing material and having opposed longitudinal ribs projecting into the recess some dis tance from the outer sides of the structure: and a bumper block of yielding material mounted in the recess and having independently formed grooves in opposite faces thereof to receive the ribs, said bumper block extending beyond one side and one end 01- .the structure.

ERNEST R. MITCHELL,
